Thank you for your reply Terry . This is a subject that is dear to us all . Normal maintenance will have us grease the zerk fittings where they are found but as we know , the centering ball ISNT greasable since there is no zero fitting anywhere on its flange nor does the grease injected into the crosses reach the centering ball. You've made the case , the centering ball MUST be greased independently . It isn't possible to determine the life expextancy of the centering ball since all our driving habits vary . It's interesting that spicer willingly sells u-joints without zero fittings . We've been taught that greasing u-joints is preventive maintenance but that can't be accomplished without zero fittings. I suppose if there were machining tolerances for a zerk fitting to be installed into the centering ball flange , spicer would have provided it with one. I'd say there isn't a flange / centering ball available in this size with a zerk fitting so that leaves us to handle it as an indivdual . Some things will never change.
